Abstract: In various examples, a deep neural network (DNN) is trained—using image data alone—to accurately predict distances to objects, obstacles, and/or a detected free-space boundary. The DNN may be trained with ground truth data that is generated using sensor data representative of motion of an ego-vehicle and/or sensor data from any number of depth predicting sensors—such as, without limitation, RADAR sensors, LIDAR sensors, and/or SONAR sensors. The DNN may be trained using two or more loss functions each corresponding to a particular portion of the environment that depth is predicted for, such that—in deployment—more accurate depth estimates for objects, obstacles, and/or the detected free-space boundary are computed by the DNN.

Abstract: Configurations for interface panels are disclosed. In at least one embodiment, an interface panel includes removable receptacles to provide communication to rack components.

Abstract: Various embodiments include a network for transmitting data words from a source node to a destination node. The source node optionally inverts the logic levels of each data word so that the number of logic ‘1’ bits in each data word is less than or equal to half of the data bits. The destination node recovers the original data words by passing the data words not inverted by the source node and inverting the data words that were inverted by the source node. As the packet is transmitted through the network, each node encodes and/or decodes the data words by generating an output transition for each logic ‘1’ bit of the input data word. Because no more than half the bits of the input data word are logic ‘1’ bits, the node generates output transitions for no more than one half of the data bits.

Abstract: Apparatuses, systems, and techniques to perform federated training of neural networks while maintaining control over dissemination of local models of neural networks from which aspects of local training data might be extracted. In at least one embodiment, a neural network is trained on local training data and a local model is provided to be aggregated with other local models into a global model that is in turn used for further local model training, wherein a provided local model or training is adjusted to reduce an ability to extract aspects of local training data therefrom.

Abstract: In various examples, detected object data representative of locations of detected objects in a field of view may be determined. One or more clusters of the detected objects may be generated based at least in part on the locations and features of the cluster may be determined for use as inputs to a machine learning model(s). A confidence score, computed by the machine learning model(s) based at least in part on the inputs, may be received, where the confidence score may be representative of a probability that the cluster corresponds to an object depicted at least partially in the field of view. Further examples provide approaches for determining ground truth data for training object detectors, such as for determining coverage values for ground truth objects using associated shapes, and for determining soft coverage values for ground truth objects.

Abstract: In various examples, the present disclosure relates to using temporal filters for automated real-time classification. The technology described herein improves the performance of a multiclass classifier that may be used to classify a temporal sequence of input signals—such as input signals representative of video frames. A performance improvement may be achieved, at least in part, by applying a temporal filter to an output of the multiclass classifier. For example, the temporal filter may leverage classifications associated with preceding input signals to improve the final classification given to a subsequent signal. In some embodiments, the temporal filter may also use data from a confusion matrix to correct for the probable occurrence of certain types of classification errors. The temporal filter may be a linear filter, a nonlinear filter, an adaptive filter, and/or a statistical filter.

Abstract: In various examples, at least partial control of a vehicle may be transferred to a control system remote from the vehicle. Sensor data may be received from a sensor(s) of the vehicle and the sensor data may be encoded to generate encoded sensor data. The encoded sensor data may be transmitted to the control system for display on a virtual reality headset of the control system. Control data may be received by the vehicle and from the control system that may be representative of a control input(s) from the control system, and actuation by an actuation component(s) of the vehicle may be caused based on the control input.

Abstract: A bounding volume is used to approximate the space an object occupies. If a more precise understanding beyond an approximation is required, the object itself is then inspected to determine what space it occupies. Often, a simple volume (such as an axis-aligned box) is used as bounding volume to approximate the space occupied by an object. But objects can be arbitrary, complicated shapes. So a simple volume often does not fit the object very well. That causes a lot of space that is not occupied by the object to be included in the approximation of the space being occupied by the object. Hardware-based techniques are disclosed herein, for example, for efficiently using multiple bounding volumes (such as axis-aligned bounding boxes) to represent, in effect, an arbitrarily shaped bounding volume to better fit the object, and for using such arbitrary bounding volumes to improve performance in applications such as ray tracing.

Abstract: Systems and methods are described herein for implementing a mutable device ownership transfer (DOT) of a device. An example system receives a request from a first customer to record a mutable DOT of a device using a First Customer Authentication Key (FCAK); receives the FCAK from the first customer in response to receiving the request; determines whether the device is capable of recording the mutable DOT; and installs, using a DOT circuitry, the FCAK in a non-volatile memory of a Root of Trust (RoT) associated with the device in an instance in which the device is capable of recording the mutable DOT. Installing the FCAK in the non-volatile memory of the Root of Trust (RoT) results in no permanent modification to the device.

Abstract: The disclosure relates to the transfer of per-pixel transparency information using video codecs that do not provide an alpha channel (alternatively referred to as “transparency-agnostic video codecs”). For example, alpha information of visual elements may be transcoded into the supported channels of a video stream to generate additional samples of a supported color space, which are representative of the alpha information. After being encoded by a “transparency-agnostic video codec” and transmitted, the received alpha information may then be extracted from the supported channels of the video stream to render the received visuals with corresponding per-pixel transparency.

Abstract: Systems and methods for cooling a datacenter are disclosed. In at least one embodiment, a first interfacing flow controller includes a sensor and is associated with a first server tray of a rack, so that a first interfacing flow controller can receive sensor inputs and can communicate with a second interfacing flow controller by a communication line there between, where a second interfacing flow controller can be associated with a coolant distribution unit (CDU) to cause a balance of coolant flow to be provided from a CDU to one or more second server trays based in part on a change in a coolant flow to a first server tray as indicated by such sensor inputs.

Abstract: A hardware-based traversal coprocessor provides acceleration of tree traversal operations searching for intersections between primitives represented in a tree data structure and a ray. The primitives may include triangles used in generating a virtual scene. The hardware-based traversal coprocessor is configured to properly handle numerically challenging computations at or near edges and/or vertices of primitives and/or ensure that a single intersection is reported when a ray intersects a surface formed by primitives at or near edges and/or vertices of the primitives.

Abstract: Systems and methods for cooling a datacenter are disclosed. In at least one embodiment, a cold plate is coupled to a condenser section of a heat pipe and to a primary computing device, with the heat pipe coupled to an auxiliary computing device at an evaporator section of the heat pipe, so that the cold plate draws heat from the primary computing device and from the heat pipe.

Abstract: Disclosed approaches provide for interactions of light transport paths in a virtual environment to share directional radiance when rendering a scene. Directional radiance that may be shared includes outgoing directional radiance of interactions, incoming directional radiance of interactions, and/or information derived therefrom. The shared directional radiance may be used for various purposes, such as computing lighting contributions at one or more interactions of a light transport path, and/or for path guiding. Directional radiance of an interaction may be shared with another interaction when the interaction is sufficiently similar (e.g., in radiance direction) to serve as an approximation of a sample for the other interaction. Sharing directional radiance may provide for online learning of directional radiance, which may build finite element approximations of light fields at the interactions.

Abstract: Annotations can be correlated to components of a document image so that the annotations track movements of the document image. A transparent overlay is generated to include the annotations and is linked to various components of the document image. Movement of the underlying document image is tracked and then adjustments in components positions are applied to associated annotations to maintain a contextual relationship between the annotations and the components of the document image.

Abstract: Configurations for communication interfaces are disclosed. In at least one embodiment, a processor includes one or more circuits to determine a firmware configuration for one or more server components and to transmit the firmware configuration at startup.

Abstract: In various examples, data representing user interactions with a plurality of games are analyzed to generate an aggregate playstyle profile for each game. The aggregate playstyle profiles of games participated in a by a user may be used to recommend one or more other games with a similar aggregate playstyle profile. In embodiments, an individual user's playstyle patterns may be used to determine games having similar playstyle profiles to eh user's playstyle patterns. In this way, game recommendations are more tailored to a particular type of gameplay, and not only to particular genres of games or games that are currently the most popular.

Abstract: In various examples, metadata of either a live stream game instance or a pre-recorded game instance may be included in a stream data from a game stream and used to enable access to play an instance of a game. A viewer of the stream may desire to participate in an instance of the game, and the system may use the metadata to determine authentication for the viewer with respect to a game platform hosting the game, access restrictions for the viewer with respect to the game, identification information for the streamer of the instance of the game, and/or game modification information for the particular instance of the game within the stream. This information may be used to seamlessly transition the viewer from a passive role in viewing the stream of the instance of the game on a streaming platform to actively participating in the instance of the game or another instance of the game on a gaming platform.
